Abstract: A stator winding structure of a motor or a generator includes plural separate different-shaped rod conductors combined to form a collective winding structure to take the place of a conventional winding structure which has a coil wire wound continuously. The different-shaped rod conductors can be designed in shape to match with the sizes of the coil slots to increase a slot occupied rate of the conductors and to prevent the conductors from bent during the coil winding process. The stator winding structure is especially applicable to a motor or a generator with large power and difficult in multi-electrode winding, facilitating winding and enhancing a slot occupied rate of the conductors and also reducing copper loss during output of large current.

Abstract: A third wheel collapsing device for a golf club cart includes a third wheel support unit consisting of a connect base having a fitting member with an upper inclined surface, and a lock block on the upper inclined surface. A spring chamber is continually formed in both the fitting member and the lock block for receiving a spring therein. A control rod is movably fitted in a center hole of both the fitting member and the lock block and through the spring, and has its lower end pivotally connected with an eccentric plate. The eccentric plate is swung up or down to move down or move up the control rod so that the lock block is also moved down to alters its position a little to firmly contact with an inner surface of a main frame of a golf club cart or to separate from the main frame, assembling or disassembling the third wheel support unit with or from the main frame.

Abstract: A third wheel collapsing device for a golf club cart includes a third wheel support frame having a U-shaped frame fixed pivotally with a third wheel and a hollow support arm fitted therein with a fit block. The support arm and the fit block respectively have insert holes and connecting holes. A support base assembled on the support arm has a pivotal shaft under the bottom and a threaded hole before the pivotal shaft for receiving an elastic lock member, which has an engage rod pressed downward by a spring and controlled by a user. The support base has a fastening frame fixed with the lower end of the main frame of a golf club cart. When the engage rod is pulled upward and removed out of the first insert hole of the support arm and the first connecting hole of the fit member, the third wheel support frame can be transversely collapsed.

Abstract: A power transmitting system for an electric car includes a brushless DC motor of low speed and high torque and a speed altering transmitting device. The speed altering transmitting device consists of two transmitting shafts and a bevel gear set with two ends respectively connected to the two transmitting shafts. The brushless DC motor has a rotor positioned around the speed altering transmitting device, and a stator positioned around the rotor. Then the two transmitting shafts are combined with two bearings respectively in two bearing bases in a front and rear cap of the brushless DC motor. Then the rotation of the brushless DC motor is directly transmitted through the speed altering transmitting device to the wheels of an electric car, without using a speed reducing gear set.

Abstract: A front wheel adjusting device for a golf cart includes a U-shaped support frame and a front wheel. The support frame has two parallel rods with inner ends respectively bored with a vertical groove. The front wheel has a shaft hole for a shaft to insert, which has its opposite ends respectively bored with a threaded hole. Two fixing members has a slide groove and a lengthwise straight groove, connected with the ends of the shaft, and a threaded rod is inserted in the straight groove of the fixing member and the threaded hole of the shaft and secured on the fixing member. Then, the two fixing members are respectively stuffed into the two parallel rods. Thus, turning the threaded rod can move up and down the shaft for adjusting the front wheel.

Abstract: An assembling type stator structure of motor includes a main body (52) of the stator having a plurality of scoop channels (53) and a plurality of disassembled radial toothlets (54) that are punched and stacked up by a plurality of silicon steel sheets. The configuration and size of the toothlets (54) are such that they can be fitted into the matching scoop channels (53). The toothlets (54) are connected to the main body (52) of stator to assemble into an assembled stator by employing of the following four methods: single positioning pin, double positioning pins, single groove-and-tongue, as well as double groove-and tongue.

Abstract: An assembling type rotor structure of brushless motor can be applied both in outer stator/inner rotor motor and inner stator/outer rotor motor. The rotor structure includes a rotor's main body having a plurality of ribs made of non-permeable material and a plurality of embedded small teeth capable to be disassembled in axial direction. These small teeth are formed by punching and stacking up a plurality of permeable silicon steel sheets, and each of these small teeth has a scoop channel having configuration and size matching those of the ribs of the rotor's main body. In this way, these small teeth of the rotor can be tightly embedded and fitted into the rotor's main body in axial direction but can not be moved in tangential nor in radial directions. Therefore, the rotor structure provides a rather firm fixation. What is more, the containing holes formed between each pair of the adjacent small teeth of embedded type can let the permanent magnets be embedded and fixed therein.

Abstract: A collapsing device for the third wheel of a golf cart includes a fixing base, a wheel frame, and a pin. The fixing base is U-shaped to form an interior hollow for the sleeve to fit in, having an insert groove respectively in each sidewall. The wheel frame has its bottom assembled with a third wheel, and its top provided with a slide groove at opposite sides and a through hole pivotally combined with a sleeve. The pin is inserted in the slide groove, having both ends protruding out of the slide sleeve and its intermediate portion clasped by a spring, which has its other end connected with a cover member fixedly mounted on the wheel frame. Thus, the pin is pulled by the spring and stuck in the upper or the lower insert groove for stabilizing the third wheel in the collapsed or the expanded condition.
